What is uniform circular motion?
Uniform circular motion describes motion in which an object moves with constant speed along a circular path.In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.
What is the acceleration of an object?
When a net force acts on that object, there is a change in velocity, and thus acceleration.
How does the four factors affects stability?
The four factors that affect stability are the center of gravity, the reaction forces, the buoyancy, and the moment of inertia. The center of gravity is the point at which the weight of an object is concentrated. It is the point at which the object balances when it is in equilibrium. If the center of gravity is located too far forward or backward, the object will be less stable and more prone to tipping over. When the object has its center of gravity located in the center, it will be more stable. The reaction forces refer to the forces that act on an object when it is in contact with another object. These forces include gravity, friction, and surface tension. If the reaction forces are not balanced, the object will be less stable. The buoyancy of an object is a measure of its ability to float in water or other fluids. The buoyancy of an object is determined by its density, shape, and size. If an object is too heavy, it will sink; if it is too light, it will float. An object’s buoyancy will affect its stability in water. The moment of inertia is a measure of an object’s resistance to changes in its rotational motion. The higher the moment of inertia, the more stable the object is. If the moment of inertia is too low, the object will be more prone to tipping over. These four factors all affect the stability of an object. The center of gravity affects the object’s balance, the reaction forces affect how the object interacts with other objects, the buoyancy affects how the object behaves in water, and the moment of inertia affects the object’s resistance to changes in its rotational motion. When these four factors are in balance, the object will be more stable.
Does speed effect the height of an ollie?
Height only affects Speed if the object is moving through a medium OTHER than a Vacuum. FRONTAL AREA of the object causes resistance to the forward motion. The 'thicker' the medium the more the resistance. I.E., Water resistance is greater than Air resistance. So, if the WIDTH of the object is constant, then the increase in Height increases the Frontal Area and increases the resistance to forward motion. Furthermore if the Force moving the object stays the same, then its Velocity will be LOWER.
What is the difference between the following terms used work study and motion study?
Work study includes a wide field of measurement tools and techniques. Motion study or method study is concerned with analysing individual human motions (like get object, put object) with a view to improving motion economy.
Which are two factors determine an objects velocity?
the two factors that determine an object's velocity is SPEED and DIRECTION.By: Arjane Lee Lagasca
Explain the factors that determine an object's kinetic energy?
There are two factors that determine and object's kinetic energy. The two main factors are mass and velocity.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
Name at least two factors that determine force of impact?
One of the factors that determine force of impact is the object's mass. Another factor that will determine the force of impact is the object's velocity.
What 2 factors determine how much kinetic energy an object has?
Mass and Velocity
What two factors determine the kinetic energy of moving object?
velocity and mass
How is motion related to velocity?
If an object is in motion it has a Velocity, which is speed and direction.
Is velocity a change in an objects motion?
Velocity is a change in an object's motion OR direction of motion.
What is the motion of an object said to be if its velocity is constant?
the object is on uniform motion
The speed of an object and the direction of its motion?
the object's 'velocity'
Does the total force on an object determine the change in the object's motion?
The total vector force on an object determines the change in its velocity. That change is also known as acceleration.
The speed and direction of an object's motion?
Its velocity vector.
